We were unable to get current information from SomnoMed for our October 2018 guide, so we republished old information. For this current guide, the information we had on file would have been over a year old and certain new fields we added in between the last guide SomnoMed responded to and this one–so the old responses were incomplete. We emailed and called the marketing contact at SomnoMed but did not receive any response for this guide. We hope SomnoMed responds next time, so it can be included again.
